If you want a lightweight pair that stays put while you run and lets you hear traffic, choose QCY Crossky C30; if you need to block out engine noise on a long flight and wear one headset from morning to night, choose Edifier V80. Both do multipoint pairing, but they solve completely different problems, and that's the real fork in the road here.
• QCY Crossky C30 — biggest strength: an open-ear C-clip design that keeps your ear canal unsealed, so you stay aware of your surroundings while the 10.8 mm dual-magnet driver handles the audio.
• QCY Crossky C30 — biggest trade-off: battery life is modest by modern standards (5.5 hours per charge, 25 hours with the case), and it doesn't seal your ears, so you get zero isolation.
• Edifier V80 — biggest strength: hybrid active noise cancellation, a 40 mm driver and a 45-hour playtime spec make it a genuine all-day, all-flight headphone.
• Edifier V80 — biggest trade-off: it's a full over-ear headphone, so it's bulkier, warmer to wear in summer, and it physically blocks the world out — the opposite of what a runner wants.
• For runners, cyclists and gym-goers → QCY Crossky C30.
• For commuters, travellers and home-office workers → Edifier V80.
The Crossky C30 is built around one idea: keep the ear open. The C-shape clip hooks over the ear rather than plugging into it, so nothing seals the canal. On a run, that means you hear cars, bikes and other people without pulling an earbud out. The acoustic ball has a mirror-like finish against a matte body, so it reads more like a piece of kit than a medical device — and at 43 g total, you barely notice it.
The spec sheet tells you what it's optimised for. Bluetooth 5.4 gives you a stable, fast link with a 15-metre range, and dual connection lets you hold two devices at once — the classic case being a movie on a tablet while a call comes in on your phone. You answer without re-pairing anything. Four microphones with ENC handling push your voice forward in noisy places, which matters if you take calls mid-workout. There's also an 80 ms low-latency mode, which is the setting you'd want for video so lip-sync doesn't drift.
The trade-offs are equally clear. 5.5 hours per charge is fine for a gym session or a commute, but it's not a full workday, and the 25-hour case figure is where most of your runtime lives. IPX4 covers sweat and light rain, not swimming. And because nothing seals your ear, bass won't hit like a closed headphone and noisy environments will bleed in. Skip it if you want isolation or marathon battery life. Buy it if you want to stay aware, stay stable, and take calls while moving.
The V80 goes the other direction entirely. It's a true wireless over-ear headphone with hybrid active noise cancellation — which means microphones inside and outside the cups work together to cancel what's around you. On a plane, a train or in an open-plan office, that's the feature that earns its keep. The earcups are over-ear (circumaural) with soft faux-leather cushions, and the whole thing is built around long sessions: lightweight materials, ergonomic pressure relief, and a foldable frame that tucks down for a bag.
The headline number is 45 hours of playtime. That's the kind of figure that means you charge it on Sunday and don't think about it again until the following weekend. Fast charging backs it up — 15 minutes gets you 8 hours, which is the "I forgot to charge before my flight" rescue. Bluetooth 5.4 keeps it current with the same generation of wireless tech as the Crossky C30, and it connects to phones, tablets and laptops alike, with multipoint letting you hop between two of them. Latency is spec'd at 60 ms. There's also a wired mode over USB-C, which is genuinely useful for Hi-Res listening or for when you'd rather not burn battery at all.
The catch is portability and awareness. This is a circumaural headphone — it's going to be warmer, it takes up bag space even folded, and by design it shuts the world out. If you run or cycle, that's a safety problem, not a feature. If you mostly sit at a desk or in a seat, it's exactly right. The 32-ohm impedance and 40 mm dynamic driver also suggest it'll play nicely with ordinary phones and laptops without extra gear. Skip it if you want to stay tuned into your surroundings. Buy it if you want quiet, comfort and endurance.
Side-by-Side: Which Should You Choose?
• Best for battery life → Edifier V80. 45 hours per charge versus 5.5 hours (25 with the case) on the Crossky C30.
• Best for staying aware of traffic → QCY Crossky C30. The open-ear clip design leaves your canal unsealed; the V80 actively shuts sound out.
• Best for noise cancellation → Edifier V80. Hybrid ANC is a core feature; the Crossky C30 has no isolation at all.
• Best for long-haul travel → Edifier V80. Foldable, ANC, 45 hours, and a 15-minute charge that buys 8 hours.
• Best for calls on the move → QCY Crossky C30. Four ENC microphones with a voice-focusing algorithm, tuned for crowded environments.
• Best for fast charging → Edifier V80. 15 minutes for 8 hours; the Crossky C30 relies on its 400 mAh case instead.
• Best for wired listening → Edifier V80. USB-C wired mode for Hi-Res audio; the Crossky C30 is wireless only, with no jack.
• Best for lighter latency → Edifier V80 at 60 ms, though the Crossky C30's 80 ms mode is close enough for most video.
• Best for low-hassle everyday carry → QCY Crossky C30. A 42.5 g case that disappears into a pocket.
If I had to pick one, I'd take the Edifier V80 for most people. Hybrid ANC, 45 hours of playtime, fast charging, a foldable frame and a wired USB-C fallback cover more of daily life — flights, offices, long stretches at a desk — than any open-ear design can. Multipoint is present and useful on both, but the V80's version serves a headphone you can wear all day without hunting for a charger. I'd only flip to the QCY Crossky C30 if running, cycling or awareness is the whole point of the purchase. In that case, no amount of noise cancelling makes the V80 the right tool.
how to pair multiple headphones
Multipoint is a per-device feature, so pairing two headphones at once isn't something you do from the phone — it's something each headphone does internally. Both the Crossky C30 and the V80 support dual connection, meaning each can hold two source devices simultaneously. Pair each headphone to its own set of devices through your normal Bluetooth menu.
how to pair multiple headphones iphone
On iPhone, open Settings, then Bluetooth, and pair each headphone separately — the Crossky C30 first, then the V80. iOS handles one active audio output at a time, so the two headsets won't both play at once. What each headphone can do on its own is hold two devices: the Crossky C30 and the V80 both support dual connection, so each can be linked to your phone and a second source.
how to pair multiple headphones on ipad
The process on iPad mirrors the iPhone: Settings, Bluetooth, then pair each headset one at a time. If you want two people listening on one iPad, iPadOS only routes audio to one Bluetooth output, so a headphone splitter or a shared wired connection is the practical route. Note the V80 supports wired USB-C, which can help in that situation; the Crossky C30 is wireless only.
how to pair multiple bluetooth headphones
Pair each headphone to your source individually, then let each one manage its own two-device multipoint links. The Crossky C30 uses Bluetooth 5.4 with a 15-metre range, and the V80 uses Bluetooth 5.4 with a 10-metre range. If you want two headsets playing the same audio, you'll need a source or adapter that supports dual audio output — standard Bluetooth pairing won't do it.
